Solomon, Susan

Susan Solomon and James Anderson showed that CFCs produce chlorine atoms and chlorine oxide under the conditions of the ozone layer and identified the CFCs emanating from everyday objects, such as cans of hair spray, refrigerators, and air conditioners, as the primary culprits in the destruction of stratospheric ozone. The CFC molecules are not very polar, and so they do not dissolve in rain or the oceans. Instead, they rise to the stratosphere, where they are exposed to ultraviolet radiation from the Sun. They readily dissociate in the presence of this radiation and form chlorine atoms, which destroy ozone by various mechanisms, one of which is... 

After the discovery of the Antarctic ozone hole" in 1985, atmospheric chemist Susan Solomon led the first expedition in 1986 specifically intended to make chemical measurements of the Antarctic atmosphere by using balloons and ground-based spectroscopy. The expedition discovered that ozone depletion occurred after polar sunrise and that the concentration of chemically active chlorine in the stratosphere was 100 times greater than had been predicted from gas-phase chemistry. Solomon s group identified chlorine as the culprit in ozone destruction and polar stratospheric clouds as the catalytic surface for the release of so much chlorine.

Does long-term ozone erosion result from chemical loss of ozone at midlatitudes in the lower stratosphere Susan Solomon made the very reasonable suggestion that the penetration of cirrus clouds and cold aerosols into the lower stratosphere initiates the conversion of inorganic chlorine to free-radical form,... 

In 1985, a British team at Halley Bay Station, Antarctica, discovered the existence of a hole in the ozone layer above that continent. This totally unexpected phenomenon needed an explanation, and Susan Solomon—a young National Oceanic and Atmospheric Administration (NOAA) scientist—first proposed a good theory for it. While attending a lecture on polar stratospheric clouds, she realized that ice crystals in the clouds might do more than just scatter light over the Antarctic. Her chemist s intuition told her that the ice crystals could provide a surface on which chemical reactions of CFG compounds could take place.

An American research team led by University of Colorado atmospheric chemist Susan Solomon (1956-) went to McMurdo in 1986 and established the link between atmospheric chlorine and the decrease in ozone concentration. The so-called smoking gim evidence of the link was the detection of chlorine monoxide (CIO) in the atmosphere over Antarctica. Since there are no natural sources of CIO in the atmosphere, it could only have been formed by the reaction shown in the first step of Rowland and Molinas proposal. 

Visual Encyclopedia of Equipment. This section was developed by Dr. Susan Montgomery at the University of Michigan. Here, a wealth of photographs and descriptions of real and ideal reactors are given. Students with visual, active, sensing, and intuitive learning styles of the Felder/Solomon Index will particularly benefit from this section.
